‘The Mortal Instruments: City Of Bones’ arrives in theaters Aug. 23! Could this be the new ‘Twilight’?

Lily Collins trades her Snow White gown for a bad-ass leather jacket in The Mortal Instruments: City Of Bones, one of the many supernatural blockbusters hitting theaters this summer. With Twilight‘s Jamie Campbell Boweras her other-worldly guide, Lily’s Clary will discover her destiny — as a half-angel demon slayer, known as a “Shadowhunter,” no less — and save two worlds from utter destruction. Yikes.

Oh, and did I mention Game of Thrones star Lena Headey plays Lily’s mom? And Pretty Little Liars executive producer Marlene King co-wrote the screenplay? You know, just in case you needed two more reasons to check out this bananas-looking movie.
